Description

Electronic atomizing device Technical Field

[0034] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Typical embodiments of the invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete. It should be understood that the embodiments of the present invention and the specific features thereof are detailed descriptions of the technical solutions of this application, and not limitations thereof. Where there is no conflict, the embodiments of the present invention and the technical features thereof can be combined with each other.

[0035] Traditional hookahs are made by placing lit charcoal above a container filled with hookah tobacco. Inhalation transfers the heat from the charcoal to the tobacco, heating it and producing smoke, which is then filtered through a water filter at the bottom of the hookah before being inhaled. However, burning charcoal poses safety hazards, and the ash is difficult to clean. While electronic hookahs exist as alternatives, they typically heat the side of the bowl or use a metal plate on top, resulting in uneven heating, an unsmooth flavor, and low tobacco utilization. To address these issues, this invention proposes an electronic atomization device.

[0036] Referring to Figures 1-5, in one embodiment of the present invention, the electronic atomizing device includes a body 100. An air intake channel 1101 and a vapor chamber 21 for containing atomizing material are sequentially arranged along the axial direction within the body 100. The inlet of the air intake channel 1101 communicates with the outside, and the opening of the vapor chamber 21 faces the outlet of the air intake channel 1101. An air heating unit 12 is installed within the air intake channel 1101 to heat the air entering the air intake channel 1101, turning it into hot air that enters the vapor chamber 21. The air heating unit 12 is suspended within the air intake channel 1101 using a multi-point support method to minimize heat conduction. The vapor chamber 21 is equipped with a vapor chamber heating unit 22 that conducts heat to the vapor chamber 21. The cold air entering the air intake channel 1101 can be heated to a set temperature by the air heating unit 12. When the user inhales, the heated air passes through the atomizing material in the bowl 21 to generate smoke. The hot air and the atomizing material are in three-dimensional, all-around contact, avoiding uneven heating. The bowl heating unit 22 conducts heat to the bowl 21, which then preheats and maintains the temperature of the atomizing material within it. The bowl heating unit 22 can accelerate the smoke output and maintain a stable smoke consistency. Thus, this invention solves the industry problems of uneven heating and unsmooth taste by using air heating and side wall preheating and heat preservation.

[0037] It is understood that the operating temperatures of the air heating unit 12 and the smoke pot heating unit 22 can be achieved by respectively setting temperature sensing devices. The controller controls the operating state of the air heating unit 12 and the smoke pot heating unit 22 based on the temperature signals fed back by the temperature sensing devices, thereby controlling the operating temperature. The implementation of operating temperature control is common knowledge in the art, and therefore will not be described in detail. In this embodiment, the operating temperature of the smoke pot heating unit 22 is lower than the operating temperature of the air heating unit 12.

[0038] Considering that air heating can easily lead to an increase in the external temperature of the main body 100, this embodiment also proposes to provide a heat insulation cylinder 11 inside the main body 100. The outer side of the heat insulation cylinder is open, and its top and bottom ends are fixed by heat insulation rings (such as rubber rings). The air intake channel 1101 is formed inside the heat insulation cylinder 11. To further reduce heat conduction, the air heating part 12 is suspended in the heat insulation cylinder 11 based on a multi-point support method. For example, the heat insulation cylinder 11 supports the outer wall of the air heating part 12 by multiple connecting rods 110 extending in the radial direction of the main body. In this embodiment, the connecting rods 110 are specifically screws.

[0039] To facilitate the addition of atomizing material and cleaning of the hookah bowl, the main body 100 includes an air intake heating assembly 1, an atomizing assembly 2, and a water container 3, which are detachably assembled along its axial direction. The heat insulation cylinder 11 is disposed on the air intake heating assembly 1, and the hookah bowl 21 is disposed on the atomizing assembly 2. The water container 3 can be a custom-made hookah bowl or a general-purpose hookah bowl; this part is not an improvement of the present invention and will not be described further. When the electronic atomizing device protected by the present invention is implemented as a market product, it may also omit the water container 3, allowing the user to assemble and use it independently.

[0040] The air intake heating assembly 1 includes a first outer shell 13, a first seat 14 with a through hole running vertically, and a heat insulation head 15 with a through hole running vertically. The atomizing assembly 2 includes a second outer shell 23, a second seat 24 with a through hole running vertically, a third seat 28 with a through hole running vertically, and an air outlet pipe 25.

[0041] The top end of the first outer shell 13 is fitted over the heat insulation head 15, and the bottom end of the first outer shell 13 is fitted over the first base 14. The top end of the second outer shell 23 is fitted over the second base 24, and the bottom end of the second outer shell 23 is fitted over the third base 28. The first base 14 and the second base 24 are connected by magnetic attraction, but other methods, such as snap-fit ​​connection, can also be used. The water filter 3 is detachably assembled over the third base 28. After the first base 14 and the second base 24 are connected, and after the water filter 3 is assembled with the third base 28, the first outer shell 13, the second outer shell 23, and the water filter 3 are combined to form the complete appearance of the main body 100.

[0042] The heat insulation head 15 has a through hole in its center. The heat insulation cylinder 11 can be a heat-resistant metal pipe with a certain thickness, such as a steel pipe. The top end of the heat insulation cylinder 11 is tightly fitted into the through hole of the heat insulation head 15 by a first rubber ring 16. For example, after the first rubber ring 16 is tightened on the outer wall and end face of the top end of the heat insulation cylinder 11, it is then embedded into the through hole of the heat insulation head 15 through a hard fit, so that all the air entering from the through hole of the heat insulation head 15 enters the interior of the heat insulation cylinder 11. The bottom end of the heat insulation cylinder 11 is tightly fitted into the through hole of the first base 14 by a second rubber ring 17. For example, after the second rubber ring 17 is tightened on the outer wall and end face of the bottom end of the heat insulation cylinder 11, it is then embedded into the through hole of the first base 14 through a hard fit.

[0043] In this embodiment, the air heating unit 12 includes a top fixing ring 121, a bottom fixing ring 122, a first thin-walled heat insulation tube 123, a heating core 124, a second thin-walled heat insulation tube 125, and a third thin-walled heat insulation tube 126.

[0044] The heating core 124 includes a ceramic heating block 1241 and a heating wire 1242 arranged axially along the body 100. Multiple heating channels running parallel to each other along the axial direction are arranged inside the ceramic heating block 1241. For example, in this embodiment, four heating channels are distributed around the central axis of the ceramic heating block 1241, and the heating wire 1242 is coiled within each heating channel. When the heating wire 1242 heats up, it heats the ceramic heating block 1241 to a set temperature, and heat exchange occurs when air passes through. A larger mass for the ceramic heating block 1241 is preferable, as it provides a larger heat capacity to prevent cold air from blowing the heating wire 1242 and the ceramic heating block 1241 cold during smoking, thus reducing the preheating effect. It is understood that the heating wire 1242 can also be replaced by other heating elements, such as heating elements or heating films, and there are no limitations on this.

[0045] The first thin-walled heat insulation tube 123 is a thin-walled steel tube, and its bottom end is sleeved on the outside of the top end of the heating core 124. A central vent hole is opened in the top fixing ring 121, and the top end of the first thin-walled heat insulation tube 123 is sleeved with and surrounds the vent hole of the top fixing ring 121. The second thin-walled heat insulation tube 125 is also a thin-walled steel tube, and its top end is sleeved on the bottom end of the heating core 124. A vent hole is opened in the bottom fixing ring 122, with the vent hole facing the opening near the tobacco bowl 21. The bottom end of the second thin-walled heat insulation tube 125 is sleeved with and surrounds the vent hole of the bottom fixing ring 122. The two ends of the third thin-walled heat insulation tube 126 are respectively sleeved with the top fixing ring 121 and the bottom fixing ring 122, and are also sleeved on the outside of the first thin-walled heat insulation tube 123, the heating core 124, and the second thin-walled heat insulation tube 125.

[0046] Specifically, the ceramic heating block 1241 is roughly cylindrical, with stepped protrusions extending radially outward at both its top and bottom ends. The bottom end of the first thin-walled heat insulation tube 123 fits over the protrusion at the top of the ceramic heating block 1241 and rests against the steps. The top end of the second thin-walled heat insulation tube 125 fits over the protrusion at the bottom of the ceramic heating block 1241 and rests against the steps. The main body of the top fixing ring 121 is a first planar circular ring. The vent of the top fixing ring 121 is a through-hole in the center of the first planar circular ring. The bottom surface of the first planar circular ring extends slightly from the edge of the vent towards the axial direction of the body 100 to form a first cylindrical portion surrounding the vent. The bottom surface of the first planar circular ring also extends towards the axial direction of the body 100 to form a second cylindrical portion, which surrounds the first cylindrical portion in a spaced manner. The first cylindrical part is fitted over the top end of the first thin-walled heat insulation tube 123, and the second cylindrical part is fitted over the top end of the third thin-walled heat insulation tube 126. The top ends of the first thin-walled heat insulation tube 123 and the third thin-walled heat insulation tube 126 abut against the bottom surface of the first planar ring.

[0047] The bottom fixing ring 122 includes a cylindrical ring and a second planar ring extending radially from approximately the waist of the inner wall of the cylindrical ring. A second rubber ring 17 is also fitted over the cylindrical ring of the bottom fixing ring 122, providing support. A through hole in the bottom fixing ring 122 extends through the center of the second planar ring. The bottom surface of the second planar ring forms a third cylindrical portion surrounding the through hole along the edge of the through hole towards the axial direction of the body 100. The edge of the third cylindrical portion extends radially toward the axis of the body 100 to form an inner flange. The bottom end of the second thin-walled heat insulation tube 125 is fitted into the third cylindrical portion and abuts against the inner flange. The top surface of the second planar ring extends axially to form a fourth cylindrical portion surrounding the through hole. The fourth cylindrical portion is fitted over the bottom end of the third thin-walled heat insulation tube 126, and the bottom end of the third thin-walled heat insulation tube 126 abuts against the top surface of the second planar ring.

[0048] To further reduce heat conduction, firstly, the cylindrical ring essentially forms the outer wall of the entire bottom fixing ring 122, and the top fixing ring 121 essentially forms the outer wall of the entire top fixing ring 121. Both are radially separated from the heat insulation cylinder 11, reducing heat conduction. Secondly, the air heating unit 12 is supported at multiple points. Screws pass through the heat insulation cylinder 11 and are detachably locked to the cylindrical ring of the bottom fixing ring 122. Simultaneously, screws pass through the heat insulation cylinder 11 and abut against the second cylindrical portion of the top fixing ring 121. Of course, in other embodiments, the screws and the top fixing ring 121 can also be detachably locked. Thus, only the screws conduct heat between the bottom fixing ring 122, the top fixing ring 121, and the heat insulation cylinder 11. The number of screws can be adjusted according to the situation. For example, the screws on the outer wall of the bottom fixing ring 122 can be three screws evenly spaced around the perimeter, meaning the angle between adjacent screws is 120°. The top fixing ring 121 essentially forms the outer wall of the entire top fixing ring 121. The screws on the top fixing ring 121 can be similarly configured.

[0049] To ensure uniform mixing of the hot air, at least one layer of filter screen can be provided at the vent positions of the bottom fixing ring 122. This filter screen and the second thin-walled heat insulation tube 125 constitute a hot air mixing space. For example, in this embodiment, a filter screen is designed, which rests on the inner flange of the third cylindrical section. The filter screen directly abuts against the bottom end of the second thin-walled heat insulation tube 125. The filter screen can be removed for cleaning by disassembling the second thin-walled heat insulation tube 125, etc.

[0050] To prevent airflow from directly entering the body 100 along the axial direction and to prevent dust and other impurities from falling into the body 100, this embodiment also installs a cover assembly 18 above the heat insulation head 15. The cover assembly 18 includes a connecting ring 182, a baffle 181, a support frame 183, and a partition 184. The connecting ring 182 is fitted inside the first outer shell 13 and positioned on the heat insulation head 15. The support frame 183 is placed flat and clamped between the connecting ring 182 and the heat insulation head 15. The support frame 183 is arched in the middle and has the baffle 181 installed thereon. The inside of the connecting ring 182 is a groove with an outwardly convex arc-shaped sidewall, and a window that runs vertically through the center of the bottom of the groove is opened. The baffle 181 is suspended above the window, that is, the window is blocked by the baffle 181, and a gap is formed between the baffle 181 and the groove wall of the connecting ring 182 as an annular air inlet. The support frame 183 has an air inlet in the arched middle section. The partition 184 is horizontally positioned and embedded within the first rubber ring 16, with a ring of air inlets distributed along its edge. The gas entering through the ring of air inlets enters the space between the partition 184 and the support frame 183, and then enters the heat insulation cylinder 11 through the ring of air inlets at the edge of the support frame 183.

[0051] The top end of the second outer shell 23 is fitted over the second base 24 and sealed with a sealing ring, and the bottom end of the second outer shell 23 is fitted over the third base 28 and sealed with a sealing ring. The tobacco bowl 21 includes an outer pot 211 and an inner pot 212 placed inside the outer pot, so the inner pot 212 can be easily removed for cleaning. The bottom of the inner pot 212 has a mesh opening, and the tobacco bowl heating part 22 is a heating film covering the outer wall of the outer pot 211. The outer pot 211 is located in the second outer shell 23, and its opening is tightly fitted into the through hole of the second base 24 by a third rubber ring 26. The bottom of the outer pot 211 is a cylindrical opening, which is supported above the third base 28 by a thin-walled heat-insulating air guide pipe 27, which can be a thin-walled steel pipe. In this way, the outer side of the outer pot 211 does not contact other structures, and the top and bottom are insulated by the third rubber ring 26 and the thin-walled heat-insulating air guide pipe 27, respectively.

[0052] The inlet of the vent pipe 25 is inserted into the through hole of the third seat 28 and is directly connected to the thin-walled heat-insulating vent pipe 27. The outlet of the vent pipe 25 is located in the water container 3. The smoke from the inner pot 212 enters the outer pot 211 through the bottom mesh, and then enters the vent pipe 25 from the bottom of the outer pot 211 through the thin-walled heat-insulating vent pipe 27. Finally, the smoke is discharged into the water container 3 from the outlet of the vent pipe 25, where the water container 3 collects the smoke discharged from the vent pipe 25.

[0053] The sidewall of the second outer casing 23 has an exposed charging interface, a temperature adjustment knob, and a smoke pipe interface for connecting to an external smoke pipe embedded in the radial direction. The charging interface and temperature adjustment knob are electrically connected to the circuit board (PCB). The temperature adjustment knob can adjust the operating temperature of the air heating unit 12 and the smoke pot heating unit 22. The charging interface allows for external power supply, solving the problems of battery space and low battery output power, increasing heating power to accelerate smoke output and increase smoke volume. It also reduces reliability issues caused by the impact of high internal temperatures on the battery. The top of the third housing 28 has an L-shaped exhaust pipe, the bottom of which runs through the entire axial direction of the third housing 28, and the top outlet of which connects to the smoke pipe interface. The water container 3 is a cylindrical container with an open top, and its inner wall is press-fitted with the outer wall of the third housing 28 using a sealing ring. A one-way valve is installed in the exhaust pipe to control that smoke can only be discharged from the water container 3 through the exhaust pipe to the external smoke pipe.

[0054] The PCB board is mounted on the third seat 28. Both the second seat 24 and the first seat 14 have positive and negative electrodes 19 and 29 extending axially. When the second seat 24 and the first seat 14 are magnetically fixed together, their electrodes 19 and 29 abut against each other to achieve electrical contact. The top edge of the heat insulation cylinder 11 has a recessed notch. The first rubber ring 16 extends out a corresponding protrusion to fit into this notch. The electronic wire 127 of the air heating unit 12 passes through the protrusion of the first rubber ring 16 and extends to the outside of the heat insulation cylinder 11 to electrically connect with the positive and negative electrodes of the first seat 14 to obtain power.

[0055] To further enhance the heat insulation effect, this embodiment also provides a heat insulation cavity near the inner side of the first outer shell 13 and the second outer shell 23. Specifically, the edges of the heat insulation head 15, the first seat 14, the second seat 24, and the third seat 28 all include annular walls extending in the axial direction. These annular walls are hollow walls with an open top and a hollow interior. The hollow walls of the top fixing ring 121 and the bottom fixing ring 122 are aligned vertically and locked together by a locking element such as a screw 146. The hollow walls of the second seat 24 and the third seat 28 are aligned vertically and locked together by a locking element such as a screw 248. Preferably, heat insulation material, such as heat insulation cotton, can be filled into the hollow area inside the hollow wall through the top opening. Thus, this embodiment can further enhance the heat insulation effect of the body 100.

[0056] The electronic atomizing device of the present invention has the following beneficial effects: On the one hand, the present invention has an air heating unit installed in the air intake channel to heat the air, turning it into hot air that enters the tobacco bowl, thereby making three-dimensional and all-round contact with the atomizing material. Moreover, the air heating unit is fixed based on a multi-point support method, which can minimize the heat loss through contact conduction. On the other hand, the tobacco bowl is equipped with a tobacco bowl heating unit that conducts heat to the tobacco bowl, thereby allowing the tobacco bowl to preheat and keep the atomizing material warm, which can accelerate the smoke output speed and maintain the stability of the smoke. Thus, the present invention can achieve this through air heating and sidewall heating. The preheating and heat preservation methods solve the industry problems of uneven heating and uneven texture. Furthermore, in order to further avoid the external heating of the main body caused by air heating, multiple heat insulation measures are designed, such as heat insulation of the heat insulation cylinder, fixing of the heating core through thin-walled heat insulation tube, and hollow wall configuration of the base. The heating core uses ceramic heating blocks and heating wires. Multiple heating channels are arranged in parallel along the axial direction inside the ceramic heating block, and the heating wire is coiled in the heating channel, which can further improve the heating effect. A filter screen and thin-walled heat insulation tube are also configured to form a hot air mixing space, so as to fully mix the hot air and avoid burning.
